About the movie camera

16 mm film 16 mm film The film with the width of 16 mm is the most widely used film in the narrow film system. 1923 was introduced to the market by Kodak Company of Heismann, which was only used by amateur film lovers to shoot family entertainment films. 16 mm silent movie screen projection size is 9? 65 mm, height 7? 2 1mm, with one perforation on each side. After entering the era of sound film, copying was changed to one-sided perforation, and the other side was used as the position of vocal cords (optical vocal cords or magnetic vocal cords). Due to the light weight of 16mm film equipment, low film and processing costs, and the continuous progress of emulsion technology, the clarity and granularity of projected images have been improved, so it is widely used in science and education, news, industry and commerce. At the same time, it is also used for making feature films in cinemas in small and medium-sized towns or projection units in remote areas. Most of the existing rural projection teams in China use 16 mm movies. 16mm film can be shot directly with 16mm film and then printed with 16mm projection copy, or reduced with standard 35mm film. On the contrary, the original film can also be shot by 16 mm system, and then enlarged and printed into a 35 mm projection copy. In addition, there is a super 16 system abroad, which is specially used to shoot and enlarge the aspect ratio of 1. 65∶ 1 35 mm non-distortion widescreen (widescreen) film. The original film shot by the system extends horizontally to the sound level area, thus making full use of the effective area of 16 mm film, simplifying the shooting work of wide-screen film and making it more flexible.
